The commenters on Reddit seem to think something's amiss. On Wednesday, a Japanese blog published a series of photos of the 2013 Miss Korea contestants, which were then posted by Redditor ShenTheWise with the caption, "Korea's plastic surgery mayhem is finally converging on the same face. Here are the miss korea 2013 contestants."
Plenty of commentators on Reddit echoed ShenTheWise's sentiments, noting that the 20 women all looked remarkably similar. (Other commenters, in turn, accused ShenTheWise of being racist.) But the similarities are worth noting,  considering South Korea has the highest rate of plastic surgery per capita worldwide.
It could also be argued that any group of pageant participants, no matter the country, tend to fit a certain standard of beauty. 
As for the Miss Korea ladies, it's unlikely that all 20 have undergone cosmetic procedures -- or that they've been Photoshopped, for that matter. But do you, like many commenters, find their resemblance to one another uncanny?
